Second-level domain principles and procedures, you can apply for the application to open [normal framework secondary domain name]
To achieve the effect of a second-level name, the conditions and procedures must be taken:
1. There must be a top-level domain name, and this domain name must be parsed well and pointed well.
2. There must be an independent server. The general resolved domain name points to the server.
3. Create an empty host header web site in IIS on the server.
4. Set the default page to your second machine parsing program (for example:)
5. Second-level domain name series programs (including application page:, add page, parsing page,)
Advantages of this program:
a. Can limit the sensitive words of the domain name application, such as hacker, www, sex, china, etc.
b. Illegal words that can be restricted from applying for domain names, such as:! ·#￥%…—*()——? '"/wait
c, Only one domain name can be applied for per address.
d. Limit the length of the domain name applied.
e. If no one applies for the domain name the user visits, go to a specific page.
f, Apply for domain name: ***. It can support access to two domain names: http://***. and http://www.***.
Here is the series of program code:
<form action= method=post name=Frm onSubmit="return check_input()"> <br> <font color=red>Add * as required</font> <br>
The domain name you want to register:
